This part of IEC 62391 applies to fixed electric double layer capacitors (called” supercapacitors”) mainly used in DC circuits of electronic equipment.
Measuring method(refer to figure: Self-discharge test diagram) Before this measurement is made, the supercapacitor shall be f···
Measurements of capacitance and internal resistance by the constant current discharge method and the d.c. resistance method, respectively require much (long) measuring time depending on the product ratings provided that the measuring conditions are standardized with specificity···
In generally, leakage current is current that flows in supercaps that is thought to be in a “off” mode where ideally no current would flow. For internation standard:IEC 62391-1,Leakeage current is a value of current that folws through a supercaps after a charge for a ···

During periods of erection work, which are often connected with down time, the user should be aware that conditions might differ from those experienced during the period of operation.
Therefore the selection of ···
Electric double-layer capacitors( EDLC capacitor ) for power are intended for applications that require discharge currents in the range from mA to A. The characteristics of the capacitors include such performance as relatively high capacitance and low internal resistance, whic···
After several rounds of competition, including expert review, online voting, and final defense, a new technology—- the new model of high energy density supercapacitor for mass transportation, developed by a subsidiary of Supreme Power Solutions Co., Ltd. (SPS) in Jiangsu···
The ultra capacitor company Supreme Power Solutions Co., Ltd. (SPS) recently has demontrated its latest development in ultra capacitor products at the 2017 PCIM (at Nuremberg). The visitors may see a wide range of ultra capacitor products at the No. 532 booth of SPS in Hall 7 of PCIM.
As the peak of the Fast and Furious franchise, Fast and Furious 8 has received enormous success at global box office with the help of cutting-the-edge technologies. The movie created a world of fantasy for the fans of vehicle racing and science fiction: Vehicles can almost fly under acc···
